The article deals with concept of ecosystem services as applied to the anthropogenic ecosystems, and in particular to the freshwater techno-ecosystems. Available reference sources showed that ecosystem services as certain benefits which human obtain/receive form the ecosystem functioning, are considered mostly in relation to the natural ecosystems. At the same time, considerable part of the biosphere already consists of aggregations of a great number of the heavily modified and artificial ecosystems. Beside services, ecosystems' functioning, and of techno-ecosystems in particular, can create certain problems to the human activities and well-being. The concept of "ecosystem anti-service, disservice" is introducing as totality of effects of the ecosystems processes, which are considered as undesirable, even harmful, dangerous to the humans and society.

the Kiev Reservoir
It has been found that in 2011-2016 global and local climatic changes in the ecosystem of the Kiev Reservoir manifested themselves in excessive summer temperatures of the water: in the surface layers of water - to 27.2-28.8°C, whereas in its near-bottom layers - to 25.9-26.6°C. The response of phytoplankton to excessive temperatures manifested itself in changes in its taxonomic diversity, abundance, structural organization, and in the processes of production and decomposition. At the present time, Chlorophyta, Bacillariophyta, and Cyanoprokaryota are highly diverse in their species composition. However, small-sized Chrysophyta and Cryptophyta also contribute significantly to the total number of phytoplankton species (8 and 5 species and 17 and 8%, respectively). Previously they occurred only in early spring. On the whole, two types of algal communities differing in their species composition, abundance, and structure are formed depending on water temperature. A direct relationship was established between the excessive temperature of water registered in summertime and the intensity of Cyanoprokaryota and Chlorophyta development. At the same time, the intensity of Bacillariophyta development depended inversely on summer temperature. The maximal values of the total, net primary production, and organic matter decomposition significantly differed from their minimal values. On the whole, the excessive summer temperatures of the water did not result in the irreversible changes in the structural and functional organization of phytoplankton belonging to the main component of the autotrophic chain of the ecosystem of the Kiev Reservoir.

The group of metals, including Li, Be, Na, Mg, K, Ca, Mn, Co, Cu, Rb, Sr, Cs, Ba, Tl, and Pb, and the sum of light (La, Ce, Pr, Nd, and Sm) and heavy (Eu, Gd, Tb, Dy, Er, Tm, Yb, and Lu) rare-earth elements, the content of which correlates with the growth of Chironomus riparius larvae, was determined in bottom sediments using the method of piecewise regression. The methods of the multidimensional statistical analysis and the appendix of the theory of indistinct sets, in particular, desirability functions were used. It has been shown that the metals of the first two groups of the Mendeleyev Table explain 79.5% of the variations of the change in larvae dimensions. The intervals of the concentrations of the general forms of chemical elements corresponding to the optimal growth of Chironomus riparius larvae were determined on the basis of the Harrington scale and function.

physiological adaptation
The features of the physiological adaptation of the native and invasive fish species to environmental conditions in small rivers of the urbanized territories were studied. It was shown that the compensatory-adaptive reaction to the toxic pollution of the environment of the Common gudgeon (Gobio gobio (L.)) was provided by increase of the metabolism intensity with predominance of anabolic processes, whereas Prussian carp (Carassius gibelio (B l o c h)) responded to pollution by the glycolysis intensification in liver without altering the other energy-intensive substances content in its tissues.

Long-term data on the spatial and temporal dynamics of chlorophyll α (Chl α) content in the near-bottom layer of water of the Rybinsk Reservoir obtained using the fluorometric method are given in the paper. Relationship between the content of Chl α in the near-bottom layer of water and that in the photosynthesizing zone and bottom sediments was analyzed. It has been shown that in terms of the average and prevailing values, the photosynthesizing zone is assigned to eutrophic category, whereas the near-bottom zone - to mesotrophic one. The obtained results supplement the present view on the processes of production in large water bodies. They suggest that the newly formed organic matter is of considerable importance in the formation of productivity of various biotopes. It has been shown that even under dynamic conditions the pattern of ecosystem functioning remains almost unchanged. Some specific features are observed in the years significantly differing in their hydrometeorological conditions.

The fractional composition of lipids in the gills, liver, kidneys and muscles in narp (Cyprinus carpio) and pike (Esox lucius) under the impact of 0.2 and 0.5 mg/dm3 of Fe3+ ions in water, which correspond to 2 and 5 maximal permissible concentrations, was studied. Changes in lipid content in fish tissues depended on Fe3+ ions concentration in water were species-specific.

The peculiarities and regularities of the formation, accumulation, and distribution of bottom sediments in large plain reservoirs of various types were analyzed on the basis of materials of long-term (1931-2015) investigations carried out in the Volga, Dnieper, Don, Kama, and Ob' reservoirs. Despite the fact that the studied reservoirs are closely similar in the conditions of their formation, they differ in their morphological, hydrological, and hydrodynamic indices, and also in their operation conditions. All these factors influence the process of the formation of bottom sediments in each reservoir. The formation of bottom sediments belongs to the main abiotic factors of the functioning of aquatic ecosystems. Modern statistically valid and projection indices of the spatial and temporal distribution of silts in large plain reservoirs were determined.
